Duraspark conversion?
I've read quite a few threads about people converting their feedback carbs to a Duraspark 2 setup, and I have a couple questions about it.
First, why would you want to do this? I have a feedback carb, and it works fine. My truck starts and runs when I want it to. Why would I want to go through the effort of doing the swap?
Thanks
Andy

Usually..we encounter problems with the computer system and no longer have timing advance or other things go wrong. in my case..it was a dead computer and it was easier to do the swap (Because well the ??? to why the computer is dead..what else is wrong that woulc cause the computer to go dead and do I want to spend the money to find that out. If your system is workign fine...then keep it as it is. That's good news.
I actually did the Duraspark2/HEI conversion..i used a Chebby HEI module out of late 70's gm vehicles fo rmy ignition..It runs really well..and my mileage increased about 3 mpg. (granted went from no timing advance to having it)

Hello,
I am hunting down a Duraspark dizzy and the rest of the stuff to convert from the feedback to the non-feedback. Violjohn78, why did you use the Chevy part? What year dizzy did you get? My non-feedback carb is in place and the truck runs great compared to before. Can't wait to get the rest of this stuff. Will all I need, then to complete this is the Duraspark distributor and the Duraspark control box? Will I need the coil from the Duraspark system? Sorry for the questions, just want to have my ducks in a row before I go to the junk yard. Thanks.

Well Used the chevy part because I didn't 'want to mess with the duraspark wiring..wiring for the HEI is simple..and it was only 12 bucks for a HEI module. so it was cheaper.
I used the stock tfi coil. and haven't had any problems, i'm not sure if you'd need to convert though, don't think so though. I just went online to NAPA's site and searched for a singla vacuum advance dizzy for my year (1984) and chose that part.
Most recommend getting teh stock duraspark wiring harness. Usually have to get it from a boneyard..there is plenty of info on doing the swapin this site..plus check out Fordsix.com going to the tech section there's a article on converting to Duraspark
